JT.Net had a link to a picture of a cop with an automatic weapon at an airport.
Tell me, just what good does it do to have some law enforcement dude with an automatic weapon standing in the airport? Is the officer going to fly with you to ensure no one tries anything? No. Is he going to offer his professional investigative skills to help ferret out explosives going through security? No. Truth is, this guy is not going to do you a bit of good once that cabin door closes.
Just like the “no liquids” rule, the “no nail clippers” rule, and all myriad of other dumb rules, its all just for show.
Do you feel any safer?
